node js pause execution code example

Example 1: node wait 10 seconds

async function init() {
  console.log(1);
  await sleep(1000);
  console.log(2);
}

function sleep(ms) {
  return new Promise((resolve) => {
    setTimeout(resolve, ms);
  });
}

// one liner
let sleep = ms => new Promise(resolve => setTimeout(resolve, ms));

Example 2: sleep in nodejs?

await sleep(1000)
function sleep(ms) {
  return new Promise((resolve) => {
    setTimeout(resolve, ms);
  });
}
